Basic or applied researches are being conducted by specialists in order to find answers to clinical problems or just to further understand the field. Students, during masters clinical programs, are trained not only in research methods, but also in practical ones, based on evidence. There are specific guidelines for professional practice, research methodology, ethics or training. Depending on the location, professionals can practice psychology under specific circumstances, a license usually being required.
The psychological phenomena can be understood and explained using information from various fields. C.S. Peirce discovered three interference modes: deduction, induction and abduction. These are largely used by psychologists. Besides the deductive-nomological reasoning, professionals also use the inductive reasoning in their explaining of different aspects. Thus, perception, memory or language can be explained by evolutionary psychologists as adaptations, results of sexual and natural selection.
The science of psychology is not only applied to mental health issues, but also to different aspects of human activity which need to be understood and solved. Fields such as human development, sports, the media, health, legal, aging, forensics along with industry, organizational setting, counseling, clinical and school positions often employ psychologists. Know-how of humanities, natural and social sciences is also used in Psychology.
Interpersonal relationships, personality, behavior, brain functioning, motivation, perception, attention, emotion and cognition are issues studied by researchers, some of whom (depth psychologists) also focus on unconscious mind. The interaction between psychological variables can be causal or correlational and it can be determined by empirical methods. As opposed or complementary to these methods, sometimes clinical psychologists appeal to the interpretation of symbols or inductive techniques.
Psychology studies the behaviors and mental functions of humans or animals. The person who practices or develops research in this field is called a psychologist. Research in psychology can be applied or basic. Social behavior and the mental functions of individuals are the subject of study for psychologists, while they also try to discover and understand underlying neurological and physiological processes.
